The number of pools on Royal Caribbean ships varies by size, with the massive Icon Class leading the fleet in 2026. The Icon of the Seas and its sister ship Star of the Seas feature seven distinct pools, including the world's first suspended infinity pool at "The Hideaway" and the largest pool at sea, "Royal Bay." In contrast, the popular Oasis Class ships (like Wonder of the Seas) typically offer four to five main pools, alongside numerous whirlpools and the "Splashaway Bay" water parks. Older, smaller ships in the Vision or Radiance Class usually have two main pools (one outdoor and one indoor "Solarium" pool). In 2026, Royal Caribbean has prioritized "water-based neighborhoods," ensuring that even on full-capacity sailings, there is a variety of swimming options ranging from high-energy party pools with DJs to adult-only serene retreats, making "pool hopping" a legitimate daily activity for cruisers.
